Dieter: Sakata describes this tesuji as the "race to capture suji" in tesuji and anti-suji of go.
Bill Spight: Sakata doesn't really call this anything. In fact, suji can be plural (as with most Japanese nouns), and I think that is the case here. Sakata refers to three tesuji. First, the two-step hane ( in the Part One diagram), second the suteishi suji (
there), and third the horikomi (i.e. throw-in) (
in Part Two).
dnerra: Someone I know likes to call this the "2-Dan-Tesuji". He says he has observed pretty consistently that 1-Dans may miss this tesuji (in a game, not as a problem of course), while 2-Dans usually get it right. I was 1-Dan when I first heard that from him, had recently missed it in a game, and decided never to miss it again :)
MattNoonan: In Essential Joseki on page 186, Rui Naiwei refers to this as the "sliding weight" method of capture, referring to the sliding weight on a balance scale.
